Our secret-agent man in the scene at the Barrett-Jackson auction in Scottsdale this week brings us this tri-wheeled oddity, a 1959 Heinkel Trojan, which went on the block earlier today. Its history can be traced to aircraft engineer Ernst Heinkel who built a prototype after seeing the similar ISO (later BMW) Isetta at the Geneva motor show. BMW beat Heinkel to market, though the Trojan remained in production, first in Germany and then in Ireland, until 1965. Still, the buying reservoir for this particular Trojan tipped at $15,500 — less than expected. It goes to show: one man's meticulously restored rarity is another's fodder for obscure puns.
